Abstract

The invention discloses a passivation device for mechanical manufacturing, and relates to the technical field of passivation. The passivation device comprises a box body, a motor is fixedly connected to the bottom of the inner wall of the box body, a telescopic rod is fixedly connected to one end of the motor, and a rotating mixing anti-adhesion mechanism is arranged in the box body. According to the passivation device for mechanical manufacturing, the rotating mixing anti-adhesion mechanism is arranged, so that through back-and-forth forward and backward rotation of a passivation pool, a circular groove and an arc-shaped groove in the passivation pool can stir and mix passivation liquid in the passivation pool in real time while the circular groove and the arc-shaped groove do not make contact with a part being passivated, and the situation that the surface of the part is damaged due to the fact that a stirring rod protruding during mixing and stirring touches the part being passivated is avoided; the rotating mixing anti-adhesion mechanism is arranged, so that a large amount of precipitates which are rotationally thrown to the passivation solution through rotating centrifugal force are thrown to adhere to the surface of an arc-shaped plate and are shaken off, and the uniformity of the passivation solution is higher.

Sliding with the inner wall of the small telescopic rod B405, the small telescopic rod A404 remote from the threaded rod 403 is hinged from the outer wall of the magnet scraper 406, and the outer wall of the magnet scraper 406 is in contact with the outer wall of the curved plate 307.
[0027] The emitting anti-precipitation mechanism 5 includes a turntable 501, a magnet A502, and the magnet A502 and the magnet B503 are magnetically phased, the magnet B503, the opening and joint plate 504, the outer wall of the opening and joint plate (504) is a curved shape, and the number of openings 504 is 80. Others, 80 of the opening plate 504 is evenly disposed at the top of the turntable 501, the elastic plate B505, the outer wall of the turntable 501 is slidably connected, and the outer wall of the magnet A502 is fixed to the inner wall of the turntable 501, the magnet A502 outer wall and the inner wall of the casing 2 The fixed connection, the opening and joint plate 504 is hinged from the inner wall of the turntable 501, and the bottom portion of the opening and closing plate 504 is fixed at one end of the elastic plate B505. The other end of the elastic plate B505 is fixed to the bottom of the inner wall of the turntable 504, and the other end of the opening and joint plate 501 is slid on one side of the turntable 501 connect.
[0028]In use, the passivation fluid is placed in the passivation tank 301 inside the casing 2, and then the mechanical manufacturing part required to passivate the passivation is hung to the inside of the passivation tank 301 and the fixing tub 304, and then the motor 1 is activated. The rod 6 is rotated, and the telescopic rod 6 is rotated by the passivation tank 301, and the passivation tank 301 is connected to the threaded threaded threaded sleeve 302, and the inner thread sleeve 302 is rotated, and the outer wall of the fixed bucket 304 is spaced 2 The inner wall is fixed, so that the fixing tub 304 remains stationary, the passive pool 301 rotates, the circular groove 306 lifts the outer wall of the fixing tub 304 by the cavity 303 while the passivation tank 301 is rotated through the passivation tank 301. The curved groove 305 of the inner wall is mixed with the circular groove 306 with the passivation liquid inside the fixed tub 304, and the arcuate plate 307 inside the curved groove 305 is rotated from the passivation tank 301 to passivate. The outer portion of the pool 301 is exterior, and the extrusion of the elastic plate A308 has a deformation. After a period of time, the motor 1 drives the telescopic rod 6 to rotate, so that the mechanical parts are passivated and soaked in a period of time, start the motor 1 to drive the retractable rod 6 to reverse, thereby The passivation tank 301 is rotated, so that the passivation tank 301 rotates back to the inner position, and the curved plate 307 rebounds back into the original position after the elastic plate A308 reflects the centrifugal force rotating through the passivation tank 301 to slide, elastic The plate A308 has again generated, and when the passivation tank 301 rises, the passivation tank 301 will extrude the air between the fixed tub 304 into the air tank 402 through the cavity 303, and then push the threaded rod 403 in the air slot 402.

In addition, when the passivation tank 301 is rotationally rising, the magnet A502 on both sides of the turntable 501 inside the passivation tank 301 is subjected to the magnetic phase of the magnet B503, so that the turntable 501 is relatively stationary and the magnet B503, the turntable 501 and passivation The pool 301 maintains a relatively rotating movement, sliding in the inner wall of the passivation tank 301, so that the turntable 501 is slidably in the inner wall of the passivation tank 301, the opening plate 504 of the inner wall of the turntable 501 is rejected under the action of the elastic plate B505. When the groove 306 is at an instant, the elastic plate B505 is ejected, thereby depositing the circular groove 306 to the passivation liquid precipitated by the surface of the turntable 501. When the ejection moment, pop up the precipitate at the bottom to the middle layer of the passivation liquid, as the passivation tank 301 continues to rotate on the outer wall of the turntable 501, the opening and joint plate 504 will pass through the inclined surface and the curve surface passivated pool 301. The bottom rotation pushes it to the inside of the turntable 501, and the extruded elastic plate B505 has a deformation. When the passivation tank 301 is forwarded and inversion, it can be bounced and returned by the inclined and curved shapes on the left and right sides of the opening and closing plate 504. The inside of the turntable 501 is removed, and the motor 1 is turned off after passivation, and the part after passivation is completed is taken.
